Recent research has documented that the Federal Reserve produces systematic errors in forecasting inflation, real GDP growth, and the unemployment rate, even though these forecasts are unbiased. We show that these systematic errors reveal that the Fed is "surprised" by real and inflationary cycles. Using a modified Mincer-Zarnowitz regression, we show that the Fed knows the state of the economy for the current quarter, but cannot predict it one quarter ahead. We further show that even allowing for an asymmetric loss function the Fed does not appear to know the state of the economy one quarter ahead.

The Federal Reserve Greenbook forecasts of real GDP, inflation and unemployment are analysed for the period 1974 to 1997. We consider whether these forecasts exhibit systematic bias, and whether efficient use is made of information, that is, whether revisions to these forecasts over time are predictable. Rather than analyse the forecasts separately for each horizon of interest, we discuss and implement methods that pool information over horizons.We conclude that there is evidence of systematic bias and of forecast smoothing of the inflation forecasts. JEL classification numbers: C12, C53.
